of tlieui afterwards became more rusted than they were at the date of 

 grading, though this did not occur to any great extent except in 1895. 

 In that year, for example, though a few of the varieties showed no rust 

 at all at the date of grading, yet onlj- one variety, Einkoru, remained 

 absolutely rust proof throughout the season. Much value would have 

 been added to the experiments if they could have been continued in 

 each locality during the three seasons, but under the circumstances 

 this was impracticable. It is hoped, however, that they have settled a 

 few things definitely and that they will furnish a valuable groundwork 

 for future experiments in this country.
